Connecting
Your
Radios
The
TNC
is
attached
to
your
transceiver(s)
via
the
radio
connector(s)
on
the
back
panel.
(See
page
5
for
back
panel
diagrams.)
The
KPC-2
and
KPC-2400
each
have
one
DB-9
connecter
labeled
RADIO,
which
is
used
for
either
VHF
or
HF.
The
KPC-1
has
one
5-pin
din
connector
labeled
RADIO,
which
is
used
for
either
VHF
or
HF.
The
KAM
has
a
DB-9
connector
labeled
VHF
RADIO
and
an
8-pin
din
connector
labeled
HF
RADIO.
The
KPC-4
has
two
DB-9
connectors
for
VHF/UHF
radio
connections
labeled
PORT
1
and
PORT
2.
Prewired
cables
are
provided
with
the
appropriate
connector
for
the
TNC
port.
Two
cables
come
out
of
the
connector.
One
with
a
speaker
plug
attached,
to
be
plugged
into
the
transceiver's
external
speaker
jack.
You
will
need
to
provide
the
mic-jack
connector
for
your
transceiver
and
wire
the
connector
to
the
other
cable.
Lines
from
this
connector
are
used
to
control
the
PTT
function
of
the
transceiver,
input
AFSK
tones
from
the
TNC,
and
provide
other
alternate
Inputs/Outputs
as
described.
The
KPC-1
comes
with
two
separate
cables.
One
for
audio
with
speaker
plugs
on
both
ends.
The
other
cable
has
a
5-pin
din
connector
on
the
end
for
the
KPC-1,
and
you
will
need
to
provide
the
mic-jack
connecter
for
your
transceiver
and
wire
it
to
the
other
end
of
this
cable.
Some
radios
may
require
adjustment
of
the
AFSK
Output
Levels
or
Equalization
of
the
received
signals.
See
the
AFSK
Output
Level
and
Calibration/Equalization
sections
for
information.
Caution:
Check
your
transceiver
manual
to
correctly
wire
the
corresponding
pins
of
the
transceiver
mic-jack.

Pins
1,
3,
5
and
6
must
be
connected
to
your
radio.
Pin
1
-
AFSK
Out
-
white
lead.
This
line
carries
the
AFSK
tones
generated
by
the
TNC
to
the
Audio
Input
(microphone)
line
of
your
transceiver,
If
your
transceiver
provides
a
DC
voltage
on
its
microphone
input,
you
must
isolate
this
voltage
from
8
C.
This
is
normally
true
for
hand-held
radios.
(See
the
Interfacing
Hand-Held
Radios
section.)
Y
Pin
2
-
XCD
-
yellow
lead.
This
line
may
be
used
to
connect
the
squelch
line
from
your
l
VHF
transceiver
if
desired.
This
connection
will
not
normally
be
required,
nor
used,
unless
operating
on
a
shared
voice
channel.
Normally
the
TNC
detects
other
signals
by
using
its
internal
software
to
determine
if
data
is
present.
If
this
pin
is
connected,
a
ground
potential
on
this
pin
will
tell
the
TNC
that
a
signal
is
present
(even
if
there
is
pm
no
data)
and
therefore
prevent
the
TNC
from
transmitting
until
the
signal
is
no
longer
present.
(See
the
CD
parameter
in
the
Commands
Manual.)
